I am putting together a 427 bbc 6-71 blower and dual Predators. My question is about the carbs. I have 1 race and 1 street. Can I run progressive linkage with the street carb as the primary? I have done alot of searching and specific info on these carbs is spotty at best. There is/was a fella known as predatorguru or somthing similar and I would really like to talk to him, or somebody that can help me out. I hope to find real world experience, not theory. Thanks for the time! mrhp

I'd suggest that you poke around on the net and read all you can find about Willard Kendig. He was the originator of the Variable Venturi Carburetor. Articles about Willard will undoubtedly lead you to other articles and others and others. Sooner or later, you will have amassed enough knowledge to be the resident VVC expert. I owned a Kendig VVC many years ago.
